OF NEW YORK, N. Y., A CORPORATION OF NEW YORK H WAIVHG DEVICE @riginal application filed November 30, 1932, Serial No. 644,956. Divided and this application filed February 15, 1933.

This invention relates to certain improvements in hair waving devices in which a preformed tress of hair is subjected to the action of an exothermic material which, when moistened, will of itself generate heat suficient to impart a so-called permanent wave to the tress.

This invention comprises a hair waving device in which a charge of exothermic material in the form of a rod is inserted into a tube of absorbent material; a perforated tube of metal or-other suitable stiff material being preferably used to provide a r1g1d support for the wound tress.

Practical embodiments of my 1nvent1on are'represented in the accompanying drawin in which ig. 1 represents the hair waving device in side elevation as in use;

Fig. 2 represents a longitudinal central section through the form of hair waving de vice in which the tress of hair is wound upon a perforated tube of stifl' material and the absorbent tube is inserted between the perforated tube and the rod of exothermic material;

Fig. 3 represents a similar section. through the form of hair waving device in which the tress is wound upon the absorbent tube and the perforated tube is inserted between the absorbent tube and the rod of exothermic material; and e Fig. 4 represents a section similar to Fig. 3, with the perforated tube omitted,

The outer wrapper is denoted by 1, which wrapper may be made of any suiable non absorbent material, such as parchment paper, foil, or the like. .The clamp is denoted by 2, which clamp may be of any well known or approved form. It is to be understoodthat any suitable protective pad, not shown herein, may be inserted between the clamp 2 and the scalp ofthe person being treated.

. Theperforated tube is denoted by 3, which" tube may be made of metal or other suitable stifi material.

The tube of absorbent material is denoted by 4, which tube is adapted to be moistened by water or by a smtable hair Serial No. 656,794.

waving solution such as that used for mois tening the tress.

The charge of exothermic material is herein shown in the form of a rod.

In the form shown in Fig. 2, the tress of rod 7 of exothermic material and the said tube of absorbent material.

In the form shown in Fig. 4, the tress of hair 9 is shown as wound upon the tube of absorbent material 4; and the perforated tube 3 is omitted; the rod of exotherm mic material 7 in'this instance being shown as inserted directly into the bore of the tube of absorbent material.

In practice, the tress 9 is wound either upon the perforated tube 3 as shown in Fig. 2 or upon the tube of absorbent naterial 4 as shown in Fi s. 3 and 4. The tress 9 may be moistene either before or after it is wound, by a suitable waving solution, such for instance as an ammonia solution. The tube of absorbent material 4 is moistened by water or by a suitable hair waving solution sudh as that used for moistening' the tress 9. The charge of exothermic material may then be inserted into the bore of the moistened tube of absorbent material, 'as shown in Fig. 2 or into the bore of the perforated tube as shown in Fig. 3 or into the bore of the moistened tube ofabsorbent material as shown in Fig. 4. The

wrapper 1 is then wrapped around the wound tress and may be secured at the scalp end of the tress by the clamp 2, the outer end of the wrapper being twisted together to close the same.

The exothermic action starts at once because of the application of moisture by the wetted tube of absorbent material to the exothermic material. Heat is thus set up within the device suflicient to impart a so- .peiidiiig application filed November 30,

- departing from the spirit and scope of my 1932, Serial No. (34l,956.

It is evident that various changes may be resorted to llivtliO construction, form and arrangement of the several parts Without invention, and hence I do not intend to be limited to the particular embodiments herein shown and described, but

\Vliat I claim is: k 1. A hair waving device comprising a perforated tube and a tube of absorbent material telescoping one within the other, and an isei-table rod of-exothei'mic material.

2. A hair Waving device comprising a perforated tube on which the tress is to be wound, a tube of absorbent material insertable into the perforated tube and adapted to be moistened, and a charge of exorthermic material insertable into the absorbent tube, said charge being in the form of a rod.

3. A hair Waving device comprising a tube of absorbent material adapted to be moistened, and a charge of exothermic material located Within said absorbent tube, said charge being in the form of a rod.

4. A hair waving device comprising a tube of absorbent material adapted to be moistened, a perforated tube telescoping Within the absorbent tube, and a charge of exothermic material located within the said perforated and absorbent tubes, said charge of a rod.
